Historical Details


Thibault de Castries wrote the book as part of building his magical society of the Onyx Dusk in turn-of-the-century San Francisco. He went so far as to claim that the 1906 earthquake was the result of his occult workings of the paramental energies of the city. Before his death in 1929, de Castries collected most of the extant copies of the work and burned them.
